In these conditions, localize the usage of important extensions and Command their use with non-Main Coding Suggestions. If possible, build interfaces that encapsulate the extensions so they are often turned off or compiled away on systems that don't assistance People extensions.
They are supposed to make code more simple and a lot more accurate/safer than most existing C++ code, devoid of lack of efficiency.
